I have a 2020 Razer Blade 15 model: RZ09-0328. I keep getting invalid secure boot. I’ve tried resetting in bios, I’ve tried the command prompt stuff. I’ve tried the usb things. NOTHING is working.

    Hi AlexFagundes, 

     

    It might be that your 2020 Razer Blade 15 (RZ09-0328) keeps resetting its Secure Boot policy and date because your CMOS / RTC battery is dead or failing, meaning the motherboard cannot retain BIOS configurations or time after a full power-off. To give you a precise, step-by-step guide, PM me your Razer laptop’s  SN: (Follow steps here: https://mysupport.razer.com/app/answers/detail/a_id/548/~/how-to-find-the-serial%2C-product%2C-or-part-number-on-a-razer-device) and link of your receipt in a PDF format: (Save the shareable files via any online drive account listed here: https://mysupport.razer.com/app/answers/detail/a_id/4011?_ga=2.197232171.544708261.1744067200-1885068520.1744067200&_gl=1*vo487o*_ga_3TRK53PM75*MTc0NDA2NzE5OS4xLjEuMTc0NDA2NzM0My4yNC4wLjA).
